Vinylidene fluoride trifluoromethylethylene copolymer.

摘要

A vinylidenefluoride-trifluoromethylethylene copolymer comprising vinylidene fluoride and trifluoromethylethylene as monomer units, said trifluoromethylethylene being contained in an amount of 0.1 to 30 mol % based on all the monomeric units in the copolymer. This copolymer is excellent in weathering resistance, corrosion resistance, electrical characteristics, and processability as well as flexibility.
